Another rumor, most likely from the same guy who spoiled stuff like E-HERO Core, DDD Caesar, and Beast-Eyes early.
And no, it doesn’t seem to actually Tribute.
As always, remember that these types of leaks/rumors/DID SOMEONE SAY RURI are UNCONFIRMED.
Raidraptor – Tribute Lanius
DARK Level 4 Winged Beast-Type Effect Monster
ATK/1800 DEF/400
The (1) and (2) effects of “Raidraptor – Tribute Lanius” can each only be used once per turn.
(1): During your Main Phase, if this card was Normal or Special Summoned this turn: You can send 1 “Raidraptor” card from your Deck to the Graveyard.
(2): During your Main Phase 2, if this card destroyed an opponent’s monster by battle this turn: You can add 1 “Rank-Up-Magic” Quick-Play Spell from your Deck to your hand. You can only Special Summon “Raidraptor” monsters for the rest of this turn.
